Abstract
A device and method are provided for facilitating extraction of a fraction from a biological sample. The biological sample includes non-desired material and a fraction-bound solid phase substrate. The device includes an input zone for receiving the biological sample therein and a phase-gate zone for receiving an isolation buffer therein. An output zone receives a reagent therein. A force is movable between a first position adjacent the input zone and a second position adjacent the output zone. The force urges the fraction-bound solid phase substrate from the input zone, through the phase-gate zone and into the output zone.

A device for facilitating extraction of a fraction from a biological sample, the biological sample including non-desired material and a fraction-bound solid phase substrate, the device comprising:
- an input zone for receiving the biological sample therein;
- a phase-gate zone for receiving an isolation buffer therein;
- an output zone for receiving a reagent therein;
- and
- a force movable between a first position adjacent the input zone and a second position adjacent the output zone;
- wherein the force urges the fraction-bound solid phase substrate from the input zone, through the phase-gate zone and into the output zone.
A device for facilitating extraction of a fraction from a biological sample, the biological sample including non-desired material and a fraction-bound solid phase substrate, the device comprising:
- an input zone for receiving the biological sample therein;
- an output zone for receiving an reagent therein;
- a pathway interconnecting the input zone and the output zone, and
- a force field movable between a first position adjacent the input zone and a second position adjacent the output zone;
- wherein the force urges the fraction-bound solid phase substrate from the input zone, through the pathway and into the output zone.
A method for facilitating extraction of a fraction from a biological sample, the biological sample including non-desired material and a fraction-bound solid phase substrate, the method comprising the steps of:
